I think that it would be a mistake to just declare a free for all one day on pot. If we want it to be legal, there needs to be structure. There should be laws legislating it, etc. The lack of legality is a consequence of a lack of business regulation, in my opinion anyway.
In other words, what I'm saying is that, when I got arrested for having weed, they made me pay a fine of like 250 bucks, and they didn't charge me or anything, it was like paying a traffic ticket. I would've rather not paid the fine, or been arrested, but all said and done, it wasn't that big of a deal. But for some one like the person that sells me weed, its a business. They are profiting from an enterprise that isn't sanctioned by the government. It's kind of like doing business without a license. If business licenses were offered to pot retailers, and there growers checked out and certified or whatever. Then we could have an orderly way to buy and sell without fear of criminals or the government.
